SCOPE OF MAINTENANCE, REPAIR AND SERVICING EXPLANATIONS This manual provides explanations, etc. concerning procedures for the inspection, maintenance, repair and servicing of the subject model. Note, however, that for engine and transmission-related component parts, this manual covers only on-vehicle inspections, adjustments, and the removal and installation procedures for major components. For detailed information concerning the inspection, checking, adjustment, disassembly and reassembly of the engine, transmission and major components after they have been removed from the vehicle, please refer to separate manuals covering the engine and the transmission.
ON-VEHICLE SERVICE "On-vehicle Service" is procedures for performing inspections and adjustments of particularly important locations with regard to the construction and for maintenance and servicing, but other inspection (for looseness, play, cracking, damage, etc.) must also be performed.
INSPECTION Under this title are presented inspection and checking procedures to be performed by using special tools and measuring instruments and by feeling, but, for actual maintenance and servicing procedures, visual inspections should always be performed as well.
DEFINITION OF TERMS STANDARD VALUE Indicates the value used as the standard for judging the quality of a part or assembly on inspection or the value to which the part or assembly is corrected and adjusted. It is given by tolerance.
LIMIT Shows the standard for judging the quality of a part or assembly on inspection and means the maximum or minimum value within which the part or assembly must be kept functionally or in strength. It is a value established outside the range of standard value.
REFERENCE VALUE Indicates the adjustment value prior to starting the work (presented in order to facilitate assembly and adjustment procedures, and so they can be completed in a shorter time).
DANGER, WARNING, AND CAUTION DANGER, WARNING, and CAUTION call special attention to a necessary action or to an action that must be avoided. The differences among DANGER, WARNING, and CAUTION are as follows: • If a DANGER is not followed, the result is severe bodily harm or even death. • If a WARNING is not followed, the result could be bodily injury. • If a CAUTION is not followed, the result could be damage to the vehicle, vehicle components or service equipment.
INDICATION OF TIGHTENING TORQUE Tightening torques (units: N⋅ m) are set to take into account the central value and the allowable tolerance. The central value is the target value, and the allowable tolerance provides the checking range for tightening torques. If bolts and nuts are not provided with tightening torques, refer to P.00-37.
MODEL INDICATIONS The following abbreviations are used in this manual for identification of model types. 2500:Indicates an engine with the 2,477mL <4D56> diesel engine. 3200:Indicates an engine with the 3,200mL <4M41> diesel engine. DOHC: Indicates an engine with the double overhead camshaft. M/T:Indicates the manual transmission. A/T:Indicates the automatic transmission. A/C:Indicates the air conditioner.
